How Electric Vehicles Work: The Role of DC Motors
Electric vehicles, specifically battery electric vehicles (BEVs), rely on DC motors for propulsion. These motors are the driving force behind the movement of electric vehicles, converting electrical energy into mechanical energy.
Unlike internal combustion engines, DC motors used in electric vehicles do not produce any tailpipe emissions. They are also highly efficient, converting over 85 percent of electrical energy into mechanical energy, making them a vital component in improving the overall efficiency of electric vehicles.
When an electric vehicle is in operation, electrical energy is drawn from the vehicle’s battery and supplied to the DC motor.

“While only around 20 percent of the energy in gasoline is actually used to propel an ICE vehicle forward, electric motors in EVs achieve energy losses of around 31-35 percent before factoring in energy regeneration.
The greater energy consumption of ICE vehicles stems from the inherent inefficiencies in the combustion process. Gasoline combustion engines produce excess heat and waste energy through friction, resulting in substantial energy waste. On the other hand, electric motors convert electrical energy into mechanical energy with remarkable efficiency, minimizing energy losses along the way.
By using DC motors, electric vehicles require significantly less energy to cover the same distance compared to their gasoline counterparts. This decreased energy consumption contributes to environmental sustainability by reducing carbon emissions and dependence on fossil fuels. The efficiency gains of electric motors in EVs also translate to cost savings for consumers in the form of reduced energy consumption and lower operating costs.
It’s worth noting that the efficiency comparison between electric motors and internal combustion engines does not include energy regeneration. Energy regeneration refers to the process of capturing and converting energy from braking or deceleration back into usable electrical energy. This regenerative feature further enhances the efficiency of electric vehicles, making them an even more compelling option in terms of overall energy consumption.
With their superior energy efficiency, electric motors in electric vehicles are reshaping the landscape of transportation.
